PIERRE, S.D. (AP) — The U.S. Attorney in South Dakota says a 22-year-old Rosebud man was sentenced to 18 months in prison after being convicted of stabbing a man in the back over a handshake he deemed too hard.

U.S. Attorney Randolph Seiler says Rodney Roubideaux pleaded guilty on October 7th to assault with a dangerous weapon and assault resulting in serious bodily injury.

Prosecutors say Roubideaux was drinking at a home in Ring Thunder on May 9th when he became agitated and complained that an individual shook his hand too hard. They say that after an argument, Roubideaux stood by himself in the corner of the kitchen before turning quickly and stabbing the man in the back with a kitchen knife.

Roubideaux was turned over to the custody of the U.S. Marshals Service.
